ORNL advancing LDH sorbent to recover lithium from geothermal brine wastes

Green Car Congress

Those brines can contain as much as 250 to 300 parts-per-million lithium. The LDH sorbent is made up of layers of the materials, separated by water molecules and hydroxide ions that create space, allowing lithium chloride to enter more readily than other ions such as sodium and potassium.

Lund researchers develop optimized two-phase enzymatic process for production of biodiesel

Green Car Congress

Researchers at Lund University (Sweden) have developed an optimized two-phase enzymatic (lipase) system for the conversion of plant oils to biodiesel. This part is oriented towards the organic layer, such that the lipid can easily enter the active site and the hydrophilic products can diffuse into the aqueous layer.
